HI ! I'M WALTER WATER DROP,
WOULD YOU LIKE TO HEAR ABOUT ME ?
I'M A SMALL FRIENDLY WATER DROP,
MY FRIENDS AND I MAKE THE RIVERS/ LAKES,
AND OCEANS, WE ARE THE WATER FISH LIVE IN/
BOATS SAIL ON AND CHILDREN SWIM IN AT
SANDY BEACHES,
WE ALSO VISIT PEOPLE IN THEIR HOUSES,
I LIKE TO VISIT HOUSES AND HELP BOYS AND
GIRLS/ MOTHERS AND FATHERS, I'VE JUST BEEN
ON A VISIT TO KEVIN'S HOUSE, NEXT I MIGHT
COME TO YOUR HOUSE,
-1-

COLOR ME FRIENDLY
-2-
-------
DO YOU KNOW WHAT HAPPENED WHEN I VISITED AT
KEVIN'S HOUSE ? i GOT DIRTY/ THAT'S WHAT,
LET ME TELL YOU SOME OF THE WAYS WE WATER DROPS
GET DIRTY, WE WASH DISHES, SCRUB FLOORS/ WASH
CLOTHES/ GIVE BATHS/ WASH BEHIND EARS, AND CLEAN
THE BABY'S DIAPER, THAT'S RIGHT, WE HELP
TO KEEP BOYS AND GIRLS, MOTHERS AND FATHERS/
AND HOUSES CLEAN AND IT MAKES US VERY DIRTY,
-3-

COLOR ME HELPFUL
-4-
-------
I DON'T MIND GETTING DIRTY WHEN I HELP,
BUT I SURE DON'T LIKE TO STAY DIRTY, IF
I STAY DIRTY IT MAKES ME SMELL BAD AND
LOOK FUNNY, IF I STAY DIRTY THE RIVERS/
LAKES AND OCEANS WON'T BE SO GOOD FOR
FISH OR BOATS OR FOR SWIMMING AT SANDY
BEACHES, IF I STAY DIRTY I MIGHT CARRY
GERMS AND MAKE CHILDREN SICK AND THAT
IS SOMETHING NO FRIENDLY WATER DROP
WANTS TO DO,

I'M GLAD TO TELL YOU THAT KEVIN'S CITY HAS A
PLACE TO CLEAN DIRTY WATER, IT'S CALLED A
WASTEWATER TREATMENT PLANT, WOULD YOU LIKE
TO HEAR ABOUT IT ? OK/ I'LL TELL YOU,
WHEN I FINISHED AT KEVIN'S HOUSE/ I SLID DOWN
THE DRAIN WITH ALL THE DIRT I WAS CARRYING,
I RAN THROUGH SOME PIPES IN THE GROUND CALLED
SEWERS, WHEN WE WATER DROPS RUN FAST WE CAN
CARRY MORE DIRT/ SO THE SEWERS ARE BUILT
GOING DOWNHILL TO MAKE IT EASIER FOR US TO RUN,
-7-
-------
COLOR ME RUNNING
-------
SOMETIMES THE SEWERS GET TOO DEEP AND
WE CAN'T GO DOWNHILL ANYMORE, WHEN
THAT HAPPENED TO ME, I WENT THROUGH
A PUMP, THE PUMP SPUN ME AROUND AND
AROUND LIKE A CARNIVAL RIDE UNTIL I
WAS DIZZY, THEN, LIKE AN ELEVATOR, IT
PUSHED ME UP HIGH SO I COULD RUN
DOWNHILL AGAIN,
THE SEWERS ARE LIKE STREETS FOR US AND
I FOLLOWED THEM RIGHT TO THE WASTEWATER
TREATMENT PLANT,

A WASTEWATER TREATMENT PLANT IS LIKE A
FACTORY WITH PUMPS, PIPES, VALVES, MOTORS,
MACHINES AND BIG TANKS, ALL NEEDED TO MAKE
DIRTY WATER CLEAN,
AT THE PLANT IN KEVIN'S CITY, I STARTED BY
GOING THROUGH SOME BARS CALLED A SCREEN,
THE SCREEN CAUGHT STICKS, PIECES OF>APER,
AND RAGS THAT I HAD BEEN CARRYING,
s.
AFTER THE SCREEN I WENT INTO A TANK THAT
MADE ME SLOW DOWN A BIT, REMEMBER, I SAID
THAT WHEN WE WATER DROPS RUN FAST WE CAN
CARRY MORE DIRT, WHEN I SLOWED DOWN A BIT,
I HAD TO DROP SOME OF THE HEAVY PIECES OF
DIRT, CALLED GRIT, AND LET THEM FALL TO
THE BOTTOM OF THE TANK, CAN YOU GUESS
WHY THIS TANK IS CALLED A GRIT TANK?

NEXT/ I WENT INTO A BIG TANK THAT MADE ME GO
EVER SO SLOW, I ALMOST WENT TO SLEEP GOING SO
SLOW/ BUT IT MADE ME DROP ALL KINDS OF DIRT,
THE DIRT THAT I DROPPED HERE IS CALLED SLUDGE,
MAKING ME GO SLOW TO DROP THE DIRT IS CALLED
SEDIMENTATION OR SETTLING, CAN YOU GUESS WHAT THIS
TANK IS CALLED ? THAT'S RIGHT/ IT'S CALLED A
SEDIMENTATION TANK, THE SEDIMENTATION TANK HAS
EQUIPMENT IN IT TO TAKE OUT THE SLUDGE,
WHEN I CAME OUT OF THE SEDIMENTATION TANK/ I
WAS THROUGH WITH WHAT IS CALLED PRIMARY TREATMENT,
I WAS FEELING QUITE A BIT BETTER/ BUT NOT NEARLY
AS CLEAN AS I SHOULD BE,

SOME DIRT REALLY STICKS TO A FELLOW, YOU
KNOW HOW SOMETIMES YOU HAVE TO SCRUB HARD
TO GET CLEAN, WELL I STILL NEEDED A GOOD
SCRUBBING, YOU USE A WASH CLOTH TO SCRUB
WITH, BUT WE WATER DROPS ARE SCRUBBED BY
A LOT OF HELPFUL LITTLE FELLOWS CALLED
BACTERIA, THE BACTERIA ARE SO SMALL THAT
YOU CAN'T SEE THEM WITHOUT SPECIAL HELP,
THE BACTERIA DIDN'T SCRUB ME WITH A CLOTH
OR BRUSH BUT THEY DID CLEAN OFF THE DIRT
THAT i COULDN'T DROP BY MYSELF, THAT DIRT
WAS THEIR FOOD, THEY GOBBLED IT UP AND
GOT FAT WHILE I GOT CLEAN,
THE CLEANING BY THE BACTERIA IS CALLED
SECONDARY, OR SECOND STEP, TREATMENT,
-15-
-------
COLOR ME ALMOST CLEAN
-16-
-------
THERE ARE TWO WAYS THAT BACTERIA ARE KEPT IN
A WASTEWATER TREATMENT PLANT, ONE IS CALLED
ACTIVATED SLUDGE AND THE OTHER IS CALLED
TRICKLING FILTER,
IN ACTIVATED SLUDGE THE BACTERIA FLOAT AROUND
WITH US IN A BIG TANK CALLED AN AERATION TANK,
THE AERATION TANK HAS AIR BUBBLING THROUGH IT
TO KEEP US ALL MIXED TOGETHER AND TO GIVE
OXYGEN TO THE BACTERIA, I LIKED THE AERATION
TANK, THOSE BUBBLES KIND OF TICKLED,
IN A TRICKLING FILTER/ THE TANK IS FILLED
WITH ROCK OR PLASTIC FOR THE BACTERIA TO GROW
ON, WE WATER DROPS ARE SPRAYED OVER THE TOP
AND SLIDE DOWN OVER THE BACTERIA, THEY JUST
HAVE TO SIT THERE AND CLEAN US AS WE GO BY,
-17-

COLOR ME TICKLED

-------
I FINISHED UP BY GOING THROUGH ANOTHER
SEDIMENTATION TANK, THIS WAS TO MAKE ME
LEAVE THF BACTERIA IN THE PLANT, THEY TRIED
TO GET OUT AND GO TO THE RIVER WITH ME,
THEY HAD TO STAY BEHIND TO CLEAN OTHER
WATER DROPS/ AND YOU WOULDN'T WANT THEM
TO GET INTO THE RIVER BECAUSE THEY HAD ALL
THAT DIRT THAT HAD BEEN CLEANED OFF US
WATER DROPS,
-19-

COLOR ME LEAVING
-20-
-------
THE PEOPLE WHO WORK IN THE WASTEWATER TREATMENT
PLANTS ARE CALLED OPERATORS, THEY HAVE TO SEE
THAT ALL THE EQUIPMENT IS WORKING RIGHT AND
MAKE SURE THAT WE GO INTO THE RIGHT TANKS, THE
OPERATORS HAD TO INSPECT ME AND TEST ME IN THE
PLANT LABORATORY TO BE SURE THAT I WAS CLEAN
ENOUGH TO BE PUT BACK INTO THE RIVER, THE
OPERATORS ALSO HAD TO TAKE CARE OF ALL THAT DIRT
THAT I LEFT BEHIND,
I THINK THE OPERATORS ARE VERY IMPORTANT PEOPLE/
DON'T YOU ?
-21-
-------
COLOR ME PASSING MY TEST
-22-
-------
SAY/ I HOPE YOUR CITY WILL CLEAN ME UP AFTER
I VISIT YOUR HOUSE, WILL YOU DO ME A FAVOR?
ASK YOUR MOTHER AND FATHER IF YOUR CITY HAS
A NICE WASTEWATER TREATMENT PLANT WITH ENOUGH
GOOD OPERATORS, MAYBE YOU CAN VISIT YOUR
WASTEWATER TREATMENT PLANT AND WATCH THE
OPERATORS MAKE ME CLEAN,
REMEMBER/ WE WATER DROPS WANT TO BE CLEAN
BEFORE WE GO BACK TO THE RIVER,
-23-
-------
THANK YOU MR. OPERATOR
FOR MAKING ME CLEAN.
-24-
-------
COLOR ME CLEAN AND HAPPY
